My G4 Sawtooth came with an ATI Radeon 7500 in it. After updating to 9.2.1 from 9.1, the machine freezes at the desktop unless I disable all ATI extensions. I need those extensions since I have an ATI Radeon 7500. I went looking for a driver for this card, but I can't seem to find one anywhere. This make no mention of supporting the Radeon 7500, only the Radeon 7000, and those are the last mac drives ATI released. How can I get my ATI Radeon 7500 working under Mac OS 9.2.x?
